IMPROVEMENT m DUMPING-SCOWS.

Specification forming part of Letters Patent No. 173,847, dated February22, 1876; application filed January 22, 1876.

To all whom it may concern:

Be it known that I, DANIEL DAILEY, of

the city, county, and State of New York, have invented a new andImproved Dumping-Scow, of which the followin'g'is a specification:

In the accompanying drawing, Figure 1 represents a topview, Fig. 2 avertical longitudinal section on the line 0 c, Fig. 1, and Fig. 3 a

7 vertical transverse section on line x :10, Fig. 2,

of my improved dumping-scow.

Similar letters of reference indicate corresponding parts. 7'

My invention relates to an improved dumpiug-scow, from which the refusemay be more readily and conveniently dropped forsubmersion than in thepresent systems of scows; and it consists of a scow divided by alongitudinal center bulk-head and lateral bracewalls into compartments,which are each closed a by hinged bottom gates that are raised ordropped by chains winding on a top shaft.

In the drawing, A represents a dumping-- scow, which is dividedinto twosymmetrical sections by a .center bulkhead, B, that extendslongitudinalshaft, E, is supported in central bearings of the. lateral walls, andoperated by a hand-lever crank, Windlass, or other wind ing-up device.being retained by means of both gates, and being aifixed near the endsof the gates, serving to drop or close jointly both gates of acompartment. The gates of adjoining compartments on either side of thecenter-board may be connected to oneshaft, so that a certain number ofcompartments may be emptied simultaneously by releasing the shaft. Thegates are a'suitable distance below the lateral braces of the scow,Which, together with openings at the after end of the scow, admit theentering of the'water, and thereby the sweeping of the same through thescow, which facilitates, when all the gates are dropped, the submergingof the refuse, and the carrying away of the scum or lighter parts. Thesmaller size of the-compartl'nents admits the easier handling of thegates, and thereby their readier and quicker emptying,

so that the scow requires a less number of I bands, and is attended towith greater facility and dispatch.

Having thus described my invention, I cl ai m as new and desire tosecure by Letters Patent-'- A garbage-scow, separated longitudinally bya close and transversely by open-work par- Witnesses:
